Acyclovir cream is an antiviral medication used primarily for the treatment of cold sores (herpes labialis) caused by the herpes simplex virus. It works by inhibiting the replication of the virus, thereby reducing the severity and duration of symptoms.
Dosage Form:
- Strength: 5% Acyclovir
- Packaging: Available in 10g tubes.
Indications
Acyclovir cream is indicated for:
- Cold Sores: Effective in treating recurrent cold sores on the lips and face.
- Herpes Simplex Virus Infections: Helps speed up healing and reduce symptoms such as pain, burning, and itching.
How to Use
- Application: Apply a thin layer of cream to the affected area and gently rub it in. This should be done five times a day at approximately 4-hour intervals, omitting nighttime applications.
- Timing: It is most effective when applied at the first sign of a cold sore (tingling or itching). Treatment should continue for at least 4 days, but may be extended up to 10 days if healing has not occurred.
- Hygiene: Wash hands before and after application to prevent spreading the virus. Avoid contact with eyes, mouth, or mucous membranes.
Warnings and Precautions
At-Risk Populations:
- Immunocompromised Patients: Not recommended for use in individuals with weakened immune systems; they should consult a physician for appropriate treatment options.
- Pregnant Women: Should use only if clearly needed; consult a healthcare provider before use.
- Children: Generally safe for use in children over 12 years; consult a doctor for younger children.
Drug Interactions
Acyclovir cream is generally safe and does not have significant interactions with other medications. However, patients should inform their healthcare provider about all medications they are taking.
